1. Main aspects of lubrication management
The basic elements of lubrication management and maintenance include: improving the lubrication management system, optimizing the organizational structure for lubrication tasks, and establishing a lubrication management platform. It is necessary to strictly enforce the relevant regulations regarding lubrication, carry out effective management of equipment related to lubrication, conduct regular self-inspections as part of lubrication management to identify problems early and address them promptly. Specific consumption quotas should be established, and based on these quotas, appropriate usage guidelines for different time periods such as annually or quarterly should be set. Comprehensive inspection and testing of lubricants must also be carried out. For key equipment, special charts detailing various parameters should be developed. Cleaning procedures must be followed carefully to keep filters clean. Appropriate measures for recycling used oil should be put in place to ensure consistent implementation of this practice. 2 Basic purposes of lubricating mechanical equipment and selection of lubricants 2.1 Basic purposes Lubricating chemical processing machinery helps to reduce friction within it, thereby minimizing the actual damage to such machinery. At the same time, lubricants have other advantages as well. Firstly, lubricants have a cooling effect; under conditions of high intensity and heavy workload, chemical processing machinery may heat up due to prolonged operation. In such cases, it is not only impossible to use conventional cooling methods nor can the operation be stopped – instead, lubricants are used to reduce the temperature. 2.2 Selection of lubricants: When chemical processing machinery is in operation, failures can occur, but such failures are mainly caused by an inappropriate choice of lubricants. Therefore, using the right lubricants also helps to ensure the steady operation of the machinery. For our company, lubricating oils with an ISO VG68 viscosity grade are recommended as they are suitable for bearing lubrication. The amount to be injected should be done in accordance with the instructions; if the pump is operating properly, the loss of oil should be replenished through the oil filler cap. Check the oil level immediately after the pump starts operating. It is recommended that when using it for the first time, run the pump for about 12 hours to completely drain the lubricating oil, filter it thoroughly, and then refill it into the bearing box; thereafter, the oil should be replaced regularly every year. 3 Key Points of Lubrication Management and Maintenance Techniques 3.1 Lubrication Management Methods (1) Conduct regular inspections and thorough patrols. Chemical enterprises need to prepare appropriate inspection sheets and specific checklists based on the type of equipment in question; inspection sheets are mainly used for critical equipment, while checklists are intended for regular equipment. The basic task of routine inspections is to determine the actual lubrication status of the equipment. If any lubrication issues are detected, they must be reported immediately so that they can be resolved promptly. It is necessary to effectively implement a system of regular inspections, checking parameters such as the actual oil level in the tank, and carefully recording the details of the lubrication condition. All operational procedures must be strictly followed to ensure that the equipment is not operated under excessive temperatures or loads. (2) Organize and compile technical management materials, and ensure strict implementation. Equipment lubrication is a necessary condition for its proper operation. To enhance the organization and leadership of equipment lubrication management, ensure rational and planned use of lubricants, and improve the level of lubrication management, appropriate management systems have been established based on the company’s actual conditions, with strict adherence to these systems. (3) The third-stage filter screen shall meet the standards, and an appropriate management model shall be adopted. The filters used for the third-stage filtration must meet the following requirements: cylinder oil, hydraulic oil, air compressor oil, oils for full-loss systems, vehicle engine oil, or other oils with similar viscosity. The filters to be used are: 60-mesh for the first stage, 80-mesh for the second stage, and 100-mesh for the third stage. 3.2 Key points of maintenance techniques (1) Use multi-stage oil to reduce initial wear. When the equipment has just been started up, it takes a certain amount of time for the lubricating oil to reach the parts that need lubrication. During this phase, there is significant friction between the equipment components, and a single type of lubricant is not sufficient to reduce this friction during startup. However, by using multi-stage lubrication systems, this problem does not occur. It can be seen that multi-stage lubricants significantly improve the viscosity-temperature properties of the oil; they not only ensure that the oil maintains an appropriate viscosity at high temperatures, but also keep its viscosity low at low temperatures. This allows it to reach the specific lubrication points more quickly, thereby enhancing the lubrication performance, reducing wear during the initial stages of equipment operation, and saving energy. (2) Use high-performance, high-quality lubricants to control the frequency of maintenance for chemical equipment. The development of mechanical equipment these days is characterized by smaller sizes and the ability to operate for extended periods of time. High-quality lubricants that are widely used today typically contain large amounts of efficient additives; through chemical reactions between these polar substances and the components of the equipment, a chemical adsorption film is formed. This film reduces friction, which leads to different selection criteria for new-generation lubricants compared to traditional ones. The original method for selecting lubricants for existing equipment emphasized transferring an appropriate amount of oil to the oil film in the mating areas of the equipment, and choosing the viscosity of the lubricant based on the actual speed of rotation. This approach was suitable for using pure mineral oils as lubricants, but it was not appropriate for selecting high-performance lubricants. Polar additives can improve the adsorption mechanism at a fundamental level; as a result, the chemical adsorption film formed tends to have better adsorption capabilities than those of conventional lubricants. This improved lubrication performance helps to overcome the problem of high friction caused by the inability of the oil to reach the mating areas, making it unnecessary to rely on speed-based criteria for selecting the viscosity of the lubricant. (3) Actively promote solid lubricants. Solid lubrication primarily uses materials with outstanding individual properties such as solid powders and thin films as lubricants, in order to control the internal friction of gears and thereby reduce wear on components. Solid lubrication measures generally involve the careful selection of materials, ensuring that the chosen components and equipment possess various advantages such as low pollution levels, high temperature resistance, etc. Inserted bearings have these characteristics, and moreover, no lubricating oil is required during operation. 4 Conclusion In summary, as enterprises strive to improve production efficiency and economic benefits, they need to pay attention to chemical processing machinery and equipment, focusing on regular maintenance and basic upkeep. Only in this way can operational faults be addressed promptly, potential problems eliminated, and economic losses resulting from equipment failures reduced. This ensures the steady progress of production, thereby bringing greater economic benefits to the enterprise.
